摘要：This study aimed to evaluate the initial growth of aroeira in Oxisol soil with the addition of different organic (humus and vermicompost) and organic/mineral substrates (commercial substrate) and rock powder. Seeds were collected and, after germination, transplanted to different types of substrate. The treatments assembled, with different proportions of compounds, were: T1 (50% humus 50% Oxisol); T2 (50% commercial substrate 50% Oxisol); T3 (50% vermicompost 50% Oxisol); T4 (40% humus 40% Oxisol 20% rock powder); T5 (40% commercial substrate 40% Oxisol 20% rock powder); T6 (40% vermicompost 40% Oxisol 20% rock powder); T7 (30% humus 30% Oxisol 40% rock powder); T8 (30% commercial substrate 30% Oxisol 40% rock powder); and T9 (30% vermicompost 30% Oxisol 40% rock powder). Initial plant development was influenced by the treatments; 20% powder and 40% nitrogen from humus (T4) produced seedlings with the greatest root, aerial part and total weight, in addition to greatest height and collar diameter. The data obtained indicate that aroeira develops better when in argillaceous substrates, with the addition of 40% humus and 20% rock powder, indicating the adequacy of this composition for its initial growth.
